摘要: 介绍了三峡二期厂坝工程常规砼施工时,采用不同 浇筑方案的原位抗剪试验研究,内容包括:水平剪应力与水平位移的关系;水平剪应力与 垂 直应力的关系;残余抗剪强度与垂直应力的关系;摩擦抗剪强度与垂直应力的关系;摩擦水 平应力与水平位移的关系。试验研究成果表明:层面不铺砂浆,直接浇筑富浆砼,其层面的 胶结质量可以满足设计要求。这为三峡二期厂坝工程采用塔带机入仓提供了依据。

关键词: 原位抗剪, 试验水平剪应力, 残余抗剪强度, 摩擦抗剪强度

Abstract: The field shear tests of powerhouse dam conventional concrete with different pouring ways for Three Gorges Project(TGP)'s constructi on poriod Ⅱ were performed.The main content included five kinds of relationship s,i.e.,relationship between horizontal shear stress and horizontal displacement ,horizontal shear stress and normal stress,normal stress and residual shear resi stance ,normal stress and frictional shear resistanee,frictional horizontal stre ss and horizontal displacement.The results showed that the quality of cohesion f ace between layers could meet design requirements when constructed with rich mor tar concrete instead of paving a thin layer of mortar.The basis on pouring power house dam section concrete with towerbelt(T.B.) loaders for TGP's stage Ⅱ con stuction was provided. 
